ELECTROTHERAPEUTIC AND EXERCISING APPARATUS.

Application filed March 22, 1917.

To all whom it may concern:

Be it known that 1, JOHN H. Knnnoee, a citizen of the United States,residing at Battle Creek, in the county or" Calhoun and State ofMichigan, have invented certain new and useful Improvements inElectrotherapeutic and Exercising Apparatus, of which the followingis aspecification.

This invention relates to improvements in electro-therapeutic andexercising apparatus.

It is well-known to those skilled in electrotherapeutics that when anelectric current flows through a muscle or groups of muscles the musclesare contracted, the degree and intensity of contraction depending uponthe strength or intensity of the current employed. Each contraction ofthe muscles represents an expenditure of energy. The present inventionhas been designed to utilize this p-inciple for locally reducing theamount of adipose tissue at any desired part of the body of the patientbeing treated. l1 strong muscular contractions are induced in themuscles underlying alayer of adipose tissue the adipose tissue isconsumed to sup ply the necessary amount of energy for such contractionsand the deposit of adipose tissue at this point is thereby reduced.

, The use of faradic current for this purpose has been suggested, but Ihave discovered that a sinusoidal current is more suitable for thepurpose. This is due to the fact that it is necessary to make and breakthe circuit 01" the current flowing through the'muscle or muscle groupin ordorto produce a succession of muscular contractions, and it isdesirable that an appre ciable length of time shall elapse between thesuccessive contractions in order that the patient may not becomeexcessively fatigued.

' i i hen a circuit supplying faradic current to or making the circuithas an appreciable strength. By employing a sinusoidal current andinterrupting and establishing the circuit at the moment when the currentthroi'igh the Zero point this unpleasant sensation is no longerexperienced.

it is often desirable to treat a number of dificrent parts of theanatomy at the same time but it has been found that it' the contractionsinduced in the various parts of the body occur simultaneously it ishighly Specification of Letters Patent.

succession as desired, and furthermore, by

the provision of a distributing switch 11 make it possible to causethese contractions in several orders of succession.

The main objects of my invention are therefore 1 First, to provide animproved electrotherapeutic and exercising apparatus.

Second, to provide an improved electrotllerapeutic and exercisingapparatus by the use of which great muscular activity may be obtainedwithout material shock or pain or the unpleasant sensations or resultswhich are frequently an incident toelectrical treatments.

Third, to provide an improved apparatus of the class described, whichmaybe readily adapted or'adjusted to various conditions or requirements ofthe particular case or person to be treated. H

Fourth, to provide an improved apparatus of the class describedemploying a sinusoidal current.

Fifth, to provide an improved apparatus having these advantages which iscomparatively 'niple in structure, economical, and is easilv'operated.

Farther objects, and objects relating to.

structural details, will definitely appear from the detailed descriptionto follow.

I accomplish the objects of 'my invention by the devices and meansdescribed in the following specification. The invention is clearlydefined and pointed out in the claims. I i

The invention disclosed in this application is especially adapted to beused with the electro-therapeutic chair disclosed in my application,Serial No. 135,143, filed December 5, 1916, but may, Of course, beutilized with any type of electrodes for transmitting the current tothose portions of the body which it is desired to treat.

A structure which is a preferred embodimento'f my invention is clearlyillustrated in the accompanying drawing, forming a part of thisspecification, in which:

Figure l is a plan view of the, apparatus.

Fig. IV is a transverse section of the pilot switch.

Fig. V is a front end elevation of the pilot switch.

Fig. V1 is a sectional detail taken on line e e of Fig. v.

Fig. V11 is a side elevation of'the speed control means.

Fig, VIII is a diagrammatic illustration of the electrical connectionsof the apparatus.

In the drawings, similar reference characters refer to similar partsthroughout the several views and the sectional views are taken lookingin the direction of the little arrows at the ends of the section lines.

Referring to the drawings, H is a support of any suitable kind such asthe top of a table upon which is mounted a motor M controlled by asuitable switch S, there being a pilot lamp L across the supply circuitto indicate that current is supplied to the motor circuit.

The generator Gr, so designed as to produce a sinusoidal E. M. F. isconnected to the motor through a speed control apparatus comprising afriction disk J mounted upon the shaft K of the motor and a frictionwheel N which isslidably mounted upon the shaft 0 and splined thereto.The shaft generator G extends at right angles to the shaft of the motorM in such a manner that the periphery of the friction wheel comes intocontact with the face of the friction disk J. The extended end of thegenerator shaft rests in the bearin s P of the pedestal (Q. The pedestalQ is extended above the bearings P and bored to form bearings R for thescrew threaded shaft T which has a hand wheel C at one end thereof bywhich it can be rotated in the bearings R.

A screw-threaded sleeve .V is mounted upon the threaded portion of theshaft T so that when the shaft is rotated, the sleeve is movedlongitudinally of the same, the direction of movement being dependentupon the direction of rotation of the shaft. The sleeve V carries aU-shaped extension W secured to a collar X by means of pins V, thecollar being rotatably mounted in a groove Y of the sleeve Z which issecured to the friction wheel N.

The speed control apparatus just described is in general a constructionthat is well known and a further detailed description of the same isthought to beunnecessary, it being obvious that'the speed of the shaft 0can be regulated by turning the hand wheel C to move the friction wheelN across the face of the disk J.

The interrupter I comprises a shaft 9 having mounted thereon a series ofdisks in with contact blocks designated generally by the referencecharacter 2' secured therein. These contact blocks are arranged in threerows, I, II and III, as indicated in the development of the interruptershown in Fig. VIII. These rows are spaced from each other by angles of120.

The shaft 9 is mounted in bearings j which are supported upon a strip ofinsulating material is resting upon the support H. Mounted upon oppositesides of the interrupter shaft 9 are brush supports Z having transversebores m through the top thereof in which are mounted brushes a bearingagainst the surface of the interrupter disks and a spring 0 interposedbetween the brush end of the screw 72. It will be seen that the pressureof the brushes against the interrupter disks may be varied by adjustingscrew 79.

The brush supports Z are extended through the insulating strip k and thesupport H in the form of threaded rods 9 which have nuts 9* thereon forsecuring the supporting posts to the strip is and also for attachingconnecting wires to the supportingpost Z, the supporting posts beingmade of conducting material so as to conduct current to the brushes it.

Mounted upon the front end of the shaft 9 is a sprocket wheel 8 which isgeared to the small sprocket t on the end of the shaft 0 by means of thechain u. The ratio of the gears s and t and the width of the contactblocks 2' upon the interrupter are so proportioned with each other andadjusted with relation to the winding of the generator G, that thebrushes n make contact with and leave contact blocks 2' at the instantwhen the potential is zero or practically zero.

It will be noted that while the rows of contact blocks upon theinterrupter are spaced by angles of 120, the brushes n are spaced fromeach other by angles of 180. It will therefore be apparent that at notime can more than one row of contacts on the interrupter be inengagement with either row of brushes. The contact blocks as, w, 3/, y,z, and 2 are only wide enough to contact with a single brush, while thecontacts w, y and .2 are sufficiently wide to bridge two adjacentbrushes.

The distributing switch P has a shaft '0 rotatable in bearings asupported upon the strip of insulation 1) which rests upon the supportH.

Mounted upon the shaft are a. series of disks 0 having contact blocksgenerally designated by the reference character d secured therein inspaced relation. These disks are secured upon the shaft by pressing theend plate 6' against the end disk and securing it to the shaft '0 bymeans of the pin f, which extends diagonally through the shaft,

contact with the brushes it.

. each oth the end plate 6" and a portion of the first disk, as shown inIII.

Mounted beneath the interrupter disks are brush holders 9 having borestherein for receiving t-ie brushes it and the springs t, the springbearing against the lower ends of thebrushes to maintain them in contactwith the disks. The brush holders g are extended through the insulatingstrip Z and the support H and, form threaded rods j which 'carry nuts 76for securing the brush holders to the insulating strip and for securingconductor wires for conductive rela tion to the brush holders 9.

Secured to the forward b- 1g 6. is disk Z" having holes m formed thereinat regular intervals. The shaft c of the distributing switch extendsbeyond the disk Z and has rigidly secured to its end an arm it, having atransverse bore 0 through the free end thereof and at right angles tothe disk Z to 'slidably receive the detent pin 19, which has a handle 9at the outer end thereof and an enlarged detent portion 7* at the otherend thereof which engages the holes m in the disk Z, it being held inplace by means of a spring 8 bearing against the inner end of theenlarged detent portion.

By means of the construction just shown, the distributing switch contactblocks may be rotated and held so that any one of the rows of contactblocks, shown in the development in Fig. VIII, may be brought into Someof the contact blocks are wide enough to bridge two opposite brushes,while others are so narrow that they merely contact with a single brush.The lines I, II, III, IV and V divide each row or" contact blocks intotwo parts, the ly r on the ri 'ht hand side of the i .ct with the righthand brushes of "he listrilnrting switch and those on the left side ofthe lines contact with the left d row of brushes. I t will be noted thatcertain of the con tact blocks in each row are connected with or bconnections such as m, if, etc, these connections being made heneath thesurface of the insulation so as to come ,ose

in contact with the brushes.

)lained arther on.

lilounted upon the support are a plurality r rh ostats A, B, C, D, E andF having pivoted contact arms a, b, 0", d, c and f" and index pointersa, b, 0, (Z, c, and 7. These rheostats are used to regulate the strengthof the current delivered to the bindudicated by the reference charac-29,)1, X, X respectively, as Figs. I and VIII.

5' slrs and 39 of the intere of conductive material so as collectorrings and the 25 is grounded on the interrupter of these connectionswill be,

shaft as indicatedin Fig. VIII, as are also the contact blocks :0, y andz and the contact blocks m, 3 and z are connected to the collector disk39 by means of connections 139, 239 and 339 respectively, which extendthrough the insulating material.

In Fig. VIII, the left hand brushes of the distributing switch arenumbered from 1 to 245 consecutively except that the brush corresponding to number 8 is missing. The brushes on the right hand side ofthe distributing switch are numbered consecutively from 25 to 1% exceptthat the brush corresponding to the number 26 is lacking. In thisfigure, the rightand left hand brushes are spaced apart at a distancegreater than the length of the contact blocks upon the rotating part ofthe distributing or pilot switch, but this is merely for convenience intracing the circuits when the various rows of contact blocks are incontact with the brushes, it being understood that each of the longercontact blocks are suliiciently long to reach from a right hand brush toa left hand brush. The lines I, II, III, IV and V indicate the centerline of each row of contact blocks. When a row of contact blocks are incontact with the brushes, the right hand brushes will contact with thoseportions of the contact blocks on the right hand side of the center lineand the left hand brushes will contact with those portions of thecontact blocks lying upon the left hand side of the center line. Thecontact blocks on the lines I, II, III, IV and V have been numbered tocorrespond with the numbering of the binding posts at the left hand sideexcept that the reference characters for each row of contact blocks hasan added characteristic letter, such as Z for the first row and m forthe second, a for the third, etc.

In Fig. VIII, the bottom row of brushes of the interrupter correspond tothe right hand row of brushes, shown in Fig. I and the top rowcorresponds to the left hand row of Fig. I.

36, 38, 411, and 13 at the top side of the interrupter. Brush 5 at theleft hand side of the distributing switch is connected to the brush 5 atthe top side of the interrupter by means of the wire 5 Brushes 41" and43* at the top of the interrupter are connected to the wires 41' and 43,respectively, by the wires an and 43", re spectively.

The wires 5*, 41* and 4?) connect the brushes 11 and 41; 43 and 43,respectively, at the top of the-interrupter with one end of theresistances A, E and C, respectively. and the wires 40*, 12 and 44:connect the brushes 40, 40, 42, 44 and 44, respeetively with'one end ofthe resistances B, D and F, respectively. The wires 27, 28, 29, 30 and31 connect brushes 27, 28, 29, 39 and 31 at the right hand side of thedistributing switch with the brushes 20, 21, 22, 23 and 2 1 at the lefthand side of the distributing switch. Brushes 13, 14, 15, 16, 17 and 18are connected with the other ends of the resistances F, E, D, C, B andA, respectively, by the wires 13, 14, 15, 16, 17 and 18, respectively.The brush 19 is connected to the wire 18 by the wire 18". The bindingposts 3, 4, 7, 10 and 11 at the bottom of Fig. VIII, are connected tothe brushes 3, 4, 7, 10 and 11 at the left side of the distributingswitch by means of the wires 3, 1, 7, 10 and 11 and the binding post 32at the bottom'of Fig. VIII is con nected to the brush 32 by means of thewire 32.

Brush 12 isconnected with the contact arm 6 of the rheostat E by means of the wire12 and contact arm d of the rheostat D is connected to brush Z by meansof the wire Z. The contact arms a, b and c of rheostats A, B and C areconnected to the binding posts 5, 6 and 9", respectively, by means ofthe wires 5, 6 and 9, respectively. Binding post 5 is connected to thesame end of the resistance A, to which the wire 5 is connected,

by means of the wire 5.

In operation, when the distributer switch is in such a position that thecontact blocks in line I bridge the brushes of the distributer switchcurrent will be delivered to the binding post 5, 5", through thefollowing paths: generator G, connections 25 25, 25, 25, 51, 5, 5 5, A,18, 18", 191, 39, 39. The connections just recited form a circuit inwhich the resistance A is in series. Binding post 5 is connected by theconductor 5" with one end of the resistance A, and binding post 5 isconnected to the adjustable contact arm a" by conductor 5 and maybeadjusted over the contact points of resistance A to shunt any desiredcurrent to the binding post 5 and 5.

Vhen the distributor switch is again shifted so that the contact blocksin line II bridge the brushes the pairs of binding posts indicated bythe reference characters X", X, X, and X, are energized through thefollowing circuits: Starting with the generator G the current flowsthrough the connections 25, 25, 25*, 25, and contact block 5". Theconnector m of the distributor switch connects contact blocks 5, 7', 9',10 and 11 in parallel. It will be noted that the last-mentioned contactblocks are in contact with the brushes at each side of the distributerswitch.

The current is ofl'ered four paths to the leftthrough the followingconnections, 7, 7, 7, 7; 9*", 9, 219, 2, 2, m 4, 4, 4, 1; 10", 10, 10,10; 11, 11, 11, 11.

It will be noted that by the above connections one of the binding postsfor each of the pairs mentioned above will be energized.

The following paths to the right from the contact block 5" are alsoofi'ered to the current,-7, 27, 27 23, 23 13, 43 43 o, 16, 10, 16 m; 929, 29 22, 22 42, 42, 42

The last four circuits include theresistances G, D, E and B, respectively, in series.

The binding post 6 is connected with the adjustable arm I) by theconductor 6". In a similar manner the binding post 9 is connected to theadjustable arm 0" by the conductor 9. The binding post 3 is connectedwith the adjustable arm by the connections 3 3, 3", m, Z, Z, l. Thebinding post 32 is connected with the adjustable arm 6 by theconnections 32, 32, 12, 12 and 12. By the above connections the pairs ofbinding posts X, X, X, X, are energized with continuous sinusoidalcurrent.

The binding posts 5 and 5 are at the same time supplied with aninterrupted sinusoidal current by means of the followingconnections,generator G, 25", 25, 25, ground connections 2', 5, 5, A,18, 18, 18", m", 19, 39, 39, 39, 39, G. The above circuit includes theresistance A in series and is interrupted once during each revolution ofthe interrupter. The binding post 5 is connected to one end of theresistance A by the conductor 5 and the binding post 5 is connected tothe adjustable arm a by the conductor 5.

With the contact brushes on line III of the distributing switch bridgingthe brushes thereof the pairs of binding posts X and X will not beenergized. The binding posts 11, 6 9, 7 and 4? will all be energized andthe binding post 3 will act as a common return for the five bindingposts first mentioned. It is intended that the binding posts 6 and 11will be connected to electrodes attached to the right and left leg,respectively. Binding posts 7 and 9 will be connected to electrodesattached to the right and left arm, respectively. Binding post l will beconnected to an electrode for the back and binding post 3 will beconnected to an elect rode for the abdomen.

From the description to follow it will appear that the electrodesattached to the binding posts 6 9 i, 11, and 7* will be energized insuccession and that the electrodes attached to the binding post 3 willact as a common return for the other electrodes.

By setting the distributing switch in this position contractions will beinduced in this order,right leg, left arm, back and abdomen, left leg,and right arm, the abdomen receiving five impulses. of current for eachimpulse administered to the remaining parts.

Starting with the contact blocks of the interrupter on the line II incontact with the lower row of brushes, one side of the resistance B isconnected with one side of the generator through the followingconnections:44l, e l- 2 ground connection, 25, 25, 25, G. The oppositeend of the resistance B is connected with the opposite side of thegenerator through the following connections :17, 17, 17, 37, 37 37 y239, 39, 39 39, G. These two sets of connections place the resistance Bin series with the generator. The binding post 6 is connected with thecontact arm 6 by the conductor 6 In this position of the interrupter theconnections from the binding post 3, which acts as a return for thecurrent from the binding post 6 as explained above, to the generator,are as follows :-3 3, 3, 3, n 2, 2, 9,, 9, n 11,-3l, 31, 31, y, 4.4, y,ground connection, 25, 25 25, G.

The connections just recited permit an impulse of current to be given tothe right leg and abdomen. If the interrupter is then revolved in adirection to bring the contact blocks on line I in contact with theupper brushes the binding posts 9 and 3 will be energized, thus givingan impulse of current to the left arm and abdomen.

The connections for thus energizing these binding posts are as follows:The binding post 9 is connected to the adjustable arm 0 by theconductor 9. One side of the resistance C is connected with thegenerator through the following connections :---43, 13 43*, m, groundconnection 25, 25, 25, G. The opposite end of the resistance C isconnected with the other side of the generator through the followingconnections: 16, 16, 16, 36, 36 36, m,'139, 39, 39, 39, G.

The. current flows from the binding post 6, to the binding post 3 andfrom there to one side of the generator through the followingconnections :3*, 3, 3, 3, n 2, 2, 9, 9, n 7, 27, 27*, w, 43, 43 m,ground connection,

If the interrupter is again revolved in the same direction the contactblocks on line HI will contact with the bottom row of brushes and inthis position of the contact blocks the binding posts 1 and 3 will beenergized, and the current will be controlled by the rheostat D. In thisposition of the interrupter contractions will be induced in the back andabdomen. The rheostat D is in series with the generator through thefollowing connections :generator G, 25 25, 25, ground connection .2, 12,42, rheostat D, 15 15, 15, 35, 35 35 s39, 39, s9,

39, back to the generator G. The binding post 4 is connected with therheostat through the following connections :-4, 4, at, at, M, Z, Z, Zand adjustable arm cl. The return path through the binding post 3coinprises the following connections :3, 3, 3, m 2 2, 9, 9 29, 29 2, 4242* 42 2, ground connection, 25, 25 25 to the generator G.

In the next position of the interrupter the contact blocks on the lineII will be in contact with the top row of brushes and the left leg andabdomen will receive an impulse of current. This means that the bindingposts 11 and 3 will be energized. The rheostat E will regulate thecurrent to these binding posts and is connected in series with thegenorator G through the following connections:G, 25 25, 25, groundconnection, y, 41 41 41 E, 1e, 14., 14, 34., as, y, 239, 39, 39, 39",tothe generator G. The binding post 11 is connected to the rheostat Ethrough the following connections :11, 11, 11, a 12, 12, 12 andadjustable arm 6. The current will flow from the binding post 11 throughthe body to the binding post 3 and the return circuit will be throughthe following connections :3, 3, 3, 3, n 2, 9, a 10, 30, 30 30 y, 41 4141 41, y, ground connection, 25, 25, 25, G.

In the next position of the interrupter the Contact blocks on the line Iwill contact with the lower row of brushes and the binding posts 7 and 3will be energized, and muscular contractions in the right arms andabdomen will be induced. The current to these binding posts is regulatedby the rheostat F which is connected in series with the generatorthrough the following connections:generator G, 25, 25, 25, groundconnection, X, 10 L0, F, 13 1 5, 33, 33, 33, X, 139, 39, 39*, 39, backto the generator G. The binding post 7 e is connected to the rheostat Fby the following connections 7 7, 7, 7, n 6, 6, 7, and an adjustable armF. The current from the binding post 7 returns from the bod to thegenerator through the following connections:bind' ing posts 3 3 3,. 3, n2, 9, 9", u", 8, 28, 28 28, :0, 10 s0 ground connection, 25, 25 back tothe generator lVhen the distributing switch is turned so that theContact blocks on the line IV bri the brushes of the distributing switchand the interrupter is rotated, cur "11 uls-es will be trans r, tted tothe binding posts 6' and 10 11, and 32 7 in order named, and the bindi uc return for the current flee" body 'rorn the binding poi and J.
